摘要
在高介电常数基片上直接制作一种微带带通滤波器,利用交叉耦合方法提高通带边缘的陡度,并在耦合谐振器中应用屏蔽线来减弱耦合系数以缩小滤波器的尺寸.所设计制作的小型微带梳状线带通滤波器的实测数据验证了此设计方法的正确性.
A microstrip bandpass filter was directly built on high dielectric constant substrate. The gradient of the passband edge was improved by employing cross coupling method. Meanwhile, in coupled resonator, shield wires were applied to decrease coupling coefficient so as to reduce the size of the filter. The design turned out to be effective with the use of actual data obtained from the filter.
